I believe that card is supposed to have a similar idea - a cheapy CI 
interface, but that the implementation is different.

As to how to proceed, you'll have to investigate what the windows driver is 
doing to communicate with the hardware on the CI interface, combined with 
working out the CI interface circuitry. 

The TT budget-ci is basically mostly done by the DEBI bus itself, but there is 
a custom GAL on there for handling the CAM detect and a few other things.
